Application filed June 28, 1915. Serial No. 36,814.

ToaZZ 'whom it may concern I Be it known that I, Gronor. E. CHARLAND, a citizen of the United States, residingat North Mankato, in the county of Nicollet and State ofMinnesota, have invented a new side wall of the car in order to uncover the I doorway in the car.

Another object of the invention is to provide novelmeans for supporting in an open position and for holding in a closed position, the upper door of the car.

It is within the province of the disclosure to improve generally and to enhance the utility of devices of'that type to which the present invention appertains.

lVith the above and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed, without departing from the spirit of theinvention.

In the accompanying drawing :Figure 1 is a vertical longitudinal section showing the inside of a car equipped with the present invention; Fig. 2 is a fragmental elevation of a car equipped with the doors hereinafter described; Fig. 3 is a fragmental vertical section taken transversely of the car on the line 33 of Fig. 1; Fig. 4 is a fragmental vertical section showing the upper door in latched or locked condition; Fig. 5 is a fragmental vertical transverse section showing the upper door uplifted; Fig. 6 is a fragmental vertical section taken adjacent one of the door jambs and showing the means for retaining the lower doors.

In the accompanying drawings, there is shown a car denoted generally by the numeral 1 and provided with a' doorway 2 defined by jambs 3, a sill 4: and a lintel 5, one of the roof beams of the car being shown at 6. The sill 4 is equipped with a longitudinal groove or guide 7.

The invention conteniplates'the use of a pair of lower doorsS which preferably are fashioned from metal. The doors 8 when in their extreme open or closed positions'rest in the groove or seat 7 in the sill 1 and at their meeting edges, the doors 8 may be equipped with projections 9 received in suitable recesses formed in the sill 4; at the base of the groove 7. One of the doors 8 is equipped with a cleat 10 which receives the edge of the other door 8, the cleat 10 being of the bifurcated form shown at 11 in Fig. 5, the element 11 being referred to hereinafter. 7 V y r Mounted .on the doors 8 are keepers .12 receiving a latch 1st pivotally mounted upon one door as shownnat 15. comprises a shown at 17 adjacent their upper ends to the doors 8, the lower ends of the links 16 being'pivoted to supports 18 mounted on the framework of the car. The invention comprises a. supplemental door 19 connected with one of the doors 8 by means of hinges 20, any suitable means being provided for holding the supplemental door 19 in a closed position. In the present instance, the holding means for the, door 19 comprises a keeper and a removable latch 21. Latches 23 are pivoted to the door jambs3 and are provided with notches 2 1 receiving the upper edges of the doors .8 to sustain the same, in a manner which will be understood clearly when Fig. 6 ofthe drawings is noted.

There is provided in carrying out the invention, an upper door 25 of any desired construction the upper edgeof the door 25 being loosely connected by means of chains The invention pair of links 16,.pivoted as beam 6 of the car, or otherwise supported,

is an eye 28 upon which is pivoted a support 29 provided in its upper edge with a seat 30 and supplied in its lower edge and nearto its free end with a groove or notch 31. Above the notch 31, the support 29 is provided with a projection 32' adapted to be engaged under circumstances to be pointed out hereinafter with a keeper 33 mounted on or adjacent to the roof of the car. At its outer end, as shown in Fig. 2, the support 29 is provided with an operating handle 34.

When all of the doors are in closed positions, the links 16 are inclined toward each other, the lower edges of the doors 8 rest in the seat or groove 7, the latch 15 is engaged with the keepers 12 on the doors 8, the latches s3 engage the upper edges of the doors 8 as shown in Fig. 6, the upper edges of the doors 8 are received in the bifurcated cleat 11 of the upper door 25, the upper edge of the upper door is engaged by the latches 27 adjacent the sides of the upper door, and in its intermediate portion, the upper edgeof the upper door is received in the notch 31 of the support 29. The doors 8 and 25, therefore, are retained in closed positions, the support 29 acting as a brace for the upper door 25. In order to I open the doors, the forward end of the support 29 is lifted until the notch 31 no longer engages the upper edge of the door 25, and the latches 27 are moved to unlocked positions. The cleat 11 on the lower edge of the door '25 is lifted oif the upper edges of the doors 8, and the support 29 is permittedto swing into a vertical position. Then, they door 25 is swung upwardly until it is substantially parallel to the roof of the car, the free forward end of the support 29 being swung upwardly until the projection 32 coacts with the keeper 33. Then a hook 35 which is pivoted'to the lintel 4 is engaged around the forward end of the sup port 29 to uphold the same, the support being in the position of Fig. 5, and the door 25 being received in the seat or groove 30 of the support 29. The support 29 may be manipulated'by means of the handle 34.

In order to open the lower doors 8,'the same are moved in opposite directions, the

tions.

Temporary fillers (not shown) maybe used if desired, along the edges ofthe several doors, in order to prevent a leakage of grain. This practice is known in the artand is frequently resorted to. 1

Having thus described the invention, what is claimed is In a device of the class described, a car having a doorway; a door loosely hinged at its upper edge to the car and movable trans- 7 versely of the car into an open position; a support pivoted at its inner-end to the roof of the car and extended beneath the door to uphold the door when the same is in an open position; andcar carried means. en- 7 gaging the support'adjacent' its outer end to uphold the support and the door; the' outer end of the support being provided with means for engaging the'upper edgeof the door when the same is closed, whereby: the support will act as a brace for the door, the loose hinging. of the door permitting the door to be engaged with said means.

In testimony that I claim the foregoing as my own, I have hereto aifixed my signature in the presence of two witnesses.
